LEDGER AND THE LIKE.

Application filed March 26, 1925, Serial No. 18,433, and in Great Britain November 25. 1924ctoenable its columnar rulingto be brought into alignment ,i-vith that of the uppermost page ofthe ledger.

The invention has for its object to provide improvements in such indicators or column markers by meansof which certain advantages shall be obtained.

In. an indicator or column marl-:er fora ledger andthe like of'the kind referred to, in accordance with this invention, the indicator or column marker is mounted on a cover of the ledger so as to have a movement similar to or approximating that of the one and movable member of a pair of parallel rulers.

Further, an, indie: tor or column marker for a ledger and the like, in accordance with this invention, comprises a carrier member adapted to be mounted on a cover ofthe ledger,.a strip bearing columnar 'rulmg similar ,to that of the Zledger pages, a holder for said str p and .means to carry I said holderonthe carrier member and cause it to have a movementsimilar to or approximating :thatofthe one and movable member of a pair of parallel rulers.

Also, the strip holderof the indicator or column marker is mounted on the carrier member through a pair of parallel links or is carried .at one end by a link and at the other end has a member. which engages a part of the carrier member and is guided thereby.

Further, the strip holder is mounted on thecarrier member .sO that itcan be moved within the ledger when not in use.

In order that the i-nvent-ion,.the r ature and objectof .which have been set forth, may be clearly and readily understood, reference will now be. made to the accompanying drawing on which three constructional =embodiments are illustrated.

Fig. 1 is an elevational View of the first en'ibodiment Fig. 2 a similar viewto Fig. 1 .butof the secondembodiment;

Fig. 3 a similar vView to Fig. 1 but of the third embodiment and Fig. .4 an end elevation of the embodiment shown in Fig.

Referring now to the constructional embodiment illustrated in Fig. l.

l is one of the covers of the ledger and 2 is the carrier member which is made of sheet metal blanked and pressed to shape with two rearwardly extending flanges 3, at. The one flange 3 is at the upper edge of the carrier member and the other flange 4 at one of its side edges. 5 is a U-shaped spring mounted on the carrier member 2 with its arms or legs extending downwardly and on opposite sides thereof. The carrier member 2 is placed on the cover 1 with its rear face in contact with the inner face thereof and its flanges 3, 4 in contact with the upper and one side edge respectively when so mounted,

' the carrier member 2 is held and positioned by the spring 5, the one arm or leg of which bears on the outer face of the cover.

7 is a strip of paper or the like which bears columnar ruling similar to that of the ledger pages and also bears indications of the purpose of the ruling. The strip 7 is l mounted in a holderG which is made of sheet metal blanked and pressed to shape with a forwardly extending flange 8 at one end and an inwardly extendingflange 9 on each of its sides for nearly the full lengths thereof. The strip 7 is passed endwaysbeneath the flanges 9 by which it is held,'the flange 8 constituting a stop or abutment to limit its end position.

10, 10 are a pair of links disposed parallel to one another and pivotally mounted at their one .ends on the front of the carrier member 2 and at their other ends on the backof the holder 6. '11 is a plate mounted on the front of the carrier member 2 and so disposed as to extend over the links 10 and the one arm or leg of the spring 5. As will be seen, the plate 11 has three outwardly pressed portions, the central raised portion straddling the arm or leg of the spring 5 and serving to hold the spring in position.

The other raised portions constitute guides for and control and limit the movements of the links 10.

Referring now to the constructional .embodiment illustrated in Fig. 2.

In this embodiment, only one link 10 is employed and this link is pivotally mounted at one end on the front face of the carrier member 2 and at its other end is pivot- Ezi ally connected with a plate 12 mounted on the back of the holder 6 and such that the pivotal connection of the link 10 therewith is brought below the lower edge of the holder 6. The plate 11 is also dispensed with, the link 10 being guided and controlled a d its movement limited by a part 13 which is integral with the carrier member The part 18 is formed by slitting the carrier member and pressing the metal between the slits outwardly. 14s is a part formed similarly to the part and designed to hold the one arm or leg of the spring 5. 15 is a part formed similarly to the parts 13, 14, with the exception that the slits are not alike, that is straight and parallel to each other. The lower slit is straight and the upper slit is cut on the arc of a circle, the radius of which is of the same length as the distance between the pivotal points of the link 10. The upper edge of the outwardly pressed metal of the part 15 is consequently of the same curvature. 16 is a plate mounted on the back of the holder Sand such as to extend below the edge of the holder. The lower end of the plate 16 is formed as a tongue 1'? which is passed behind the outwardly pressed metal of the part 15. The plate 16 also has at the root of the tongue 17, and centrally thereof, a projection 18, which, when the tongue 17 is passed behind the part 15, rests on the upper edge thereof. The holder is thus supported at one end by the link 10 and at the other end is supported and guided by the parts 16, 18, 15 so that such end moves as though it were carried by a link.

The slits ma however be strai ht andparallel with each other. In such case the part 15 will be as the parts 13, 14. Also, in such case, the plate 16 may have a projection each side of the root of the tongue 17 in lieu of a projection 18 placed centrally thereof.

Referring to the constructional embodiment illustrated in Figs. 3 and 4.

In this modification, the carrier member 2 is of lJ-shape in section, the arms or legs therof, when the carrier member is in position, extending down the front and rear faces of the cover 1. The links 10 are also pivotally mounted on. the back member of the carrier member 2 and are bent towards their upper ends so as to extend over the upper part of the carrier member 2 and then down in front of the front member of the carrier member 2. 20 are plates mounted on the rear face of the holder 6 and such as to extend below the lower edge of the holder 6. The plates 20 at their free or lower ends are hingedly attached to the free ends of the links 10. The portions of the links 10 that extend before the front member of the carrier member 2 have side ears 21 which are so spaced that the depending portions of the plates 20 are received therebetween. 22 is a plate mounted on the front member of the carrier member 2 and having ears or lugs 23 at its ends. The holder 6 can be turned about its hinged connection with the links 10 and laid upon the front member of the carrier member 2 in which position it will be held against longitudinal movement by engagement of the depending portions of the plates 20 with the ears or lugs 23.

It will be seen from the foregoing that the embodiments described with reference to Fig. 2 and Figs. 8 and 4 possess the feature that the holder 6 can be moved out of its operative position when the ledger is closed and out of use. In Fig. 2, the tongue 17 is disengaged from the part 15 and the holder 6 is then turned about the connection between the plate 12 and the link 10 in an arcuate path parallel with the face of the cover 1 into the position shown in dotted lines. In Figs. 3 and 4 the holder 6is movable forwardly about its hinged connection with the links 10 onto the inner face of the v cover 1. The embodiment shown'in Fig. 1 is not constructed so as to permit of the storing of the holder 6 within the ledger when out of use.

In the three embodiments described, the carrier member 2 is removably' mounted on the cover 1. It may however, be permanently secured thereto by pins, rivets or the like. lVhen so attached to the cover 1, the spring 5 is not required. 7

It will be understood that the several embodiments of the column marker or indicator described and illustrated possess the feature that the holder 6 can be moved in an endwise direction. This movement is provided to enable the indicator or column marker to be used with books of dilferent thicknesses. Indicators or column markers when used in conjunction with thick books possess the disadvantage that the divisions on the strip 7 come out of alignment with the columnar ruling of the pages when the book is open and this in proportion to the number of leaves that are turned. This will be evident if one takes into consideration the difierence in the distance between the side edge of the back of the book and the side edges of the top and bottom pages. The provision of an endways movable holder 6 enables the divisions of the strips 7 to be brought into alignment with the columnar ruling of the uppermost page.

What I claim is z 1. Index mechanism for the columnar ruling in books comprising a carrier member to be mounted on the cover of the book and a strip carrier mounted on the carrier member and movable in relation thereto as one member of a parallel ruler.

2. Index mechanism for the columnar ruling in books comprising a carrier member to be mounted on the cover of the book, a strip carrier and means to connect the strip carrier With the carrier member and impart to the former a movement in relation to the latter as one member of a parallel ruler.

3. Index mechanism for the columnar ruling in books comprising a carrier member to be mounted on the cover of the book, a strip carrier carried by the carrier member and linkage between the strip carrier and carrier member to impart to the former a movement similar to that of one member of a parallel ruler.

4:. Index mechanism for the columnar ruling in books comprising a carrier member to be mounted on the cover of the book,

a strip carrier disposed in relation to the carrier member, a link connecting the strip carrier at one end With the carrier member and means to guide the other end of the strip carrier in an arc-like path.

5. Index mechanism for the columnar ruling in books comprising a carrier member to be mounted on the cover of the book, a strip carrier disposed in relation to the carrier member, a link connecting the strip carrier at one end with the carrier member, an extension from the strip carrier and a curved slot in the carrier member engaged by said extension.

Dated this 12th day of March, 1925.
